The drought – what happened?

The frequent periods of drought in Rochefort has lowered the groundwater table of Tridaine to such an extent that in 2018, like in 2017, the City of Rochefort was confronted to a shortage of water. At the request of the City, Lhoist reactivated an existing well in the quarry. The quality of the water provided by this pumping solution has been analyzed day after day. It has perfectly met the needs of the City and the Abbey: it is the same water that was flowing in the Tridaine Gallery before and that flows again today.
